The 500W Air-Cooled Spindle Motor Kit is a complete, high-performance spindle solution for small to medium-sized CNC routers and engraving machines. Designed for precision machining, it features a 500W spindle motor with ER11 collet chuck, capable of running at variable speeds from 3000 to 12000 RPM, controlled via the included Mach3-compatible speed controller and power supply unit AC 220v / 110v To DC 0-110V Driver. The kit includes a 52mm aluminum mounting clamp, ensuring secure attachment to most CNC frames, and a 13-piece ER11 collet set, supporting a wide range of tool diameters. This air-cooled spindle provides efficient performance and reliability without the need for complex water cooling systems.
